Discussing money with children should not be taboo

Parents should be honest when teaching their children about finances, money guru David Bach says.

"Money should not be a taboo subject," he says. If you are in debt and experiencing money woes, share your problems with your children — don't keep them behind closed doors.

The best-selling author of "Debt Free for Life," Bach says his family taught him about investing and the value of money at an early age. His grandmother helped him buy McDonald's stock at age 7. He is passing along some of the same lessons to his own 7-year-old son, Jack.
